2002. Wasn't it through the CIA the bogus intel on WMD reached Cheney's office? So, for starters, Saddam Hussein.
The CIA and other agencies collect data. It's up to elected and appointed leaders to determine what to do with it.
Example; it wasn't the CIA's decision to invade Iraq or choose to simply carpet bomb all of Saddam's non-compliant "palaces". They simply presented what they have up through the chain of command. It's ultimately up to the CiC to make a decision as to what action to take, if any. In some cases, such as Iraq, the CiC can go to Congress and ask for their support. While much of data was classified, Congressional armed services and intelligence committees had the same data the President had.
If I remember correctly there were differing opinions within the CIA as to the authenticity of the "evidence" the CIA was relying on. Other US intel agencies as well as MI6 and the French intel were vehemently warning against the veracity of the evidence which was provided by a lone paid informant --Iraqi, I believe, but a disreputable toady. He was promised a big payout and ferried with his family to somewhere, no doubt, in the US .
All the voices raised against it said it was manufactured by Mossad. Mossad, btw, was of the opnion that the evidence was true as shit. This is the evidence Paul Wolfowitz, Doug Feith, and Richard Perle (all three militant Zionists, and two of whom were dual US-Israeli citizens, and I think one was even a former member of the Israeli Knesset) used to launch the war from Dick Cheney's Pentagon office, with Thomas "Cakewalk" Friedman, et al, cheering the way. These three, with an empty-headed US president blinking stupidly in tow, successfully launched the mighty American war machine against a puny country with an economy 1/10th the size of Denmark's that posed zero threat to us.
Four million Iraqis (two thirds of a Holocaust!!) subsequently perished, which ruffled some feathers. The hypersensitive Iraqis then formed ISIS and the horror show that that is. Yaaay, Mossad!!! When a duped Colin Powell went before the UN and made the US case for war based on the Israeli bullshit, the French ambassador to the UN committed the extreme breach of diplomatic protocol by holding a press conference in front of the UN right during Powell's speech. He begged us not to fall for this Israeli trick. For some reason, the US media forgot to cover the French ambassador's speech. But Colin Powell got wall-to-wall coverage along with effusive editorial references to Powell's majestic integrity and the awe-inspiring dignity and respect all the world held him in. (Since then, of course, he's finished).
Who wants to bet that the same wing in the CIA is the source of the "evidence" Russia runs our elections?
